How it Works

Generalized programs in training the throwing arm are ineffective and can cause further imbalances and strength deficits. Coaches are seeking ways to individualize, but lack tools and resources until now.

Discover the Benefits

In the ArmCare Specialist course you learn new key metrics evaluated using player-led dynamometry and range of motion testing.  And how to successfully integrate those metrics into customized programs for your athletes. This education is a must for any coach or clinician who wants to get the most out of their players and advance throwing health, velocity and command.

Designed to Advance Assessment and Training Practices

We are focused on teaching you how to improve throwing arm performance and health through creating individualized training programs based on dynamometry and range of motion assessments. Fatigue is the number one injury risk factor associated with throwing arm injuries as it causes weakness and compensation in throwing delivery. A program implemented without assessment may add to fatigue and create further strength deficits that can reduce resistance to throwing stress and cause poor performance.

Arm strength and range of motion are evaluated through 6 important measures focused on relative strength, shoulder balance, strength velocity ratios, arm fatigue, arm recovery and arm readiness. By having advanced knowledge of these ground breaking metrics, coaches, sports medicine specialists and athletes will be able to make the right decisions in adjusting training and workload and establish a strong performance process through our Player-First Approach that organizes observation, communication, implementation and evaluation of data.

Once complete, you will be a Certified ArmCare Specialist and be able to present your credentials publicly. The credential tells people that you are a baseball performance professional that deeply understands how to monitor the throwing arm and thinks critically in making throwing and training program adjustments to guide athletes in reaching their dreams.
